Hallo,
A few hours ago I experienced 3 consecutive panics on this freshly
installed 8.0, the last panic just 28s into boot sequence. It seems to
me that culprit could be iwi/wlan possibly with help from zfs or others.
More details even with screen-shot of the last panic follow.
I have used versions 5.3 to 6.4 on this laptop, the last one being the
most stable and smooth. A few weeks ago I moved to 8.0 (fresh install)
and since then I've been experiencing funny issues.
Last night I was writing an email when I noticed my wi-fi link was gone.
I checked /var/log/messages and saw the following:
wlan0: link state changed to DOWN
wlan0: link state changed to UP
wlan0: link state changed to DOWN
wlan0: link state changed to UP
wlan0: link state changed to DOWN
wlan0: link state changed to UP
linux: pid 6189 (skype): syscall inotify_init not implemented
ZFS NOTICE: Prefetch is disabled by default on i386 -- to enable,
add "vfs.zfs.prefetch_disable=0" to /boot/loader.conf.

behavior.

ZFS filesystem version 13
ZFS storage pool version 13
While wifi weirdness did not impressed me, I was perplexed by ZFS
messages. I checked kldstat and indeed ZFS was loaded. Note that I
have not attached any ZFS storage devices nor I have ever configured ZFS
on this laptop. And before I could investigate any further my laptop
froze and then rebooted.
After reboot I logged into X11 and was checking system logs while
waiting for background fsck to finish. I noticed that wifi was screwed
up, probably reset did not reinitialize it properly and the driver was
at lost. And as soon as fsck finished the system suddenly rebooted.
And it was getting worse. Next reboot did not even finish and the
system panicked again. At least this time I could see a message and so
I took a picture of it for your perusal:

Please note that this is just one of multiple issues I'm having since
moving from 6.4 to 8.0 and now I'm even worrying about my data etc. :(
What else would you need from me to investigate further please ?
With regards,
Martin
